{"cited_by_count":75523,"description":"This cluster of papers focuses on optimizing the freshness of information in communication networks, particularly in the context of real-time status updates, wireless networks, energy harvesting, and scheduling policies. The research explores age of information metrics, multi-hop networks, IoT monitoring systems, and queue management to minimize the age of information and improve network performance.","display_name":"Age of Information Optimization","domain_id":"3","external_ids":{"openalex":"https://openalex.org/T13553","wikipedia":"https://en.wikipedia.org/wiki/Age_of_Information"},"field_id":"17","id":"T13553","keywords":[{"display_name":"age of information","id":"age-of-information","score":0.7727,"url":"https://openalex.org/keywords/age-of-information"},{"display_name":"information freshness","id":"information-freshness","score":0.7376,"url":"https://openalex.org/keywords/information-freshness"},{"display_name":"data freshness","id":"data-freshness","score":0.2531,"url":"https://openalex.org/keywords/data-freshness"},{"display_name":"peak age of information","id":"peak-age-of-information","score":0.93,"url":"https://openalex.org/keywords/peak-age-of-information"},{"display_name":"status updates","id":"status-updates","score":0.2812,"url":"https://openalex.org/keywords/status-updates"},{"display_name":"status update systems","id":"status-update-systems","score":0.9897,"url":"https://openalex.org/keywords/status-update-systems"},{"display_name":"age of incorrect information","id":"age-of-incorrect-information","score":0.9414,"url":"https://openalex.org/keywords/age-of-incorrect-information"},{"display_name":"average age of information","id":"average-age-of-information","score":0.941,"url":"https://openalex.org/keywords/average-age-of-information"},{"display_name":"remote estimation","id":"remote-estimation","score":0.2852,"url":"https://openalex.org/keywords/remote-estimation"},{"display_name":"relative value iteration","id":"relative-value-iteration","score":0.3017,"url":"https://openalex.org/keywords/relative-value-iteration"},{"display_name":"gossip networks","id":"gossip-networks","score":0.2888,"url":"https://openalex.org/keywords/gossip-networks"},{"display_name":"Whittle index policy","id":"whittle-index-policy","score":0.201,"url":"https://openalex.org/keywords/whittle-index-policy"},{"display_name":"stale information","id":"stale-information","score":0.7105,"url":"https://openalex.org/keywords/stale-information"},{"display_name":"sensing scheduling","id":"sensing-scheduling","score":0.35,"url":"https://openalex.org/keywords/sensing-scheduling"},{"display_name":"TD3 reinforcement learning","id":"td3-reinforcement-learning","score":0.2223,"url":"https://openalex.org/keywords/td3-reinforcement-learning"},{"display_name":"heterogeneous IoT systems","id":"heterogeneous-iot-systems","score":0.2483,"url":"https://openalex.org/keywords/heterogeneous-iot-systems"}],"legacy_keywords":["Age of Information","Real-time Status Updates","Wireless Networks","Energy Harvesting","Scheduling Policies","Multi-hop Networks","IoT Monitoring Systems","Queue Management","Packet Management","Networked Control Systems"],"openalex_id":"https://openalex.org/T13553","source_created_date":"2024-01-23T15:27:18","source_updated_date":"2026-10-17T03:02:00","subfield_id":"1705","url":"/topics/T13553","works_api_url":"https://api.openalex.org/works?filter=topics.id:T13553","works_count":4725,"label":"Age of Information Optimization","provider":"openalex","revision":"dfef3ce9921732d9","taxonomy_revision":"f050b5d4780b1289","title":"Age of Information Optimization","kind":"topic-directory","aeo_cohort":"topic-directory","catalogue_revision":"f050b5d4780b1289","numeric_address":"38294069218787359","address_version":"morton4x16-v1","coordinates":[3,17,1705,13553],"answer_status":"Directory metadata; local answer requires separate source review","truth_status":"Subject descriptor, not a factual answer or a demonstrated knowledge gap","reviewed_answer":null}
